Hello everyone,
so I ran into trouble with a new machine I built recently.
It appears to be that when I enable threadirqs or use an rt-Kernel, I am getting an xrun inferno.
At first everything is fine but after a few seconds/minutes of playback I get thousands of xruns.
I am on Manjaro (KDE), the kernels I tried so far are
5.8.3-2 - working ok'ish without threadirqs enabled
5.6.19_rt12-3 - bad
5.4.59_rt36-1 - bad
The funny thing is that I had a nice running system at first (around two months ago) on the same machine, the xruns started suddenly out of the blue. (Kernel update?)
Configuration is
Ryzen 5 3600
B450 Aorus pro
Motu 1248
Manjaro KDE
I tried to higher the buffers to 2048, didn't help.
I installed an USB2 PCIe card so that I could separate the usb audio interface from other stuff and prefer its IRQ with rtirq.
Nothing helped.
What could be wrong?
I would love to hear your opinions
Best regards
Moshe Werner
